## Average rate vs unique rate vs instantaneous rate

$aR \to bP, Rate = -\frac{1}{a} \frac{d[R]}{dt} = \frac{1}{b}\frac{d[P]}{dt}$

### Average rate vs unique rate vs instantaneous rate

What is the difference between average rate, unique rate, and instantaneous rate (on a conceptual level)?

### Re: Average rate vs unique rate vs instantaneous rate

Average rate: Total Change/Total Time
Instantaneous rate: The rate of change at a particular moment
Unique rate: The rate of change of a species divided by its stoichiometric coefficient. For reactants it's negative, as it is disappearing.

What would be the purpose of finding the average or instantaneous rate of a reaction?
